Abstract
A control apparatus that controls a strobe to fire in synchronization with an end of an exposure period of an image capturing apparatus, includes a wireless communication device that communicates wirelessly with the strobe, and a controller that controls the wireless communication device, and the wireless communication device periodically sends a signal for maintaining communication with the strobe during the exposure period of the image capturing apparatus.
Claims12
A control apparatus that controls a strobe to fire in synchronization with an end of an exposure period of an image capturing apparatus, the control apparatus comprising:
- a wireless communication device that communicates wirelessly with the strobe;
- and
- a controller that controls the wireless communication device,
- wherein the wireless communication device periodically sends a signal for maintaining communication with the strobe during the exposure period of the image capturing apparatus,
- wherein the wireless communication device stops the signal, then sends a firing trigger signal to the strobe immediately before the exposure period ends.
An image capturing apparatus comprising a control apparatus that controls a strobe to fire in synchronization with an end of an exposure period of an image capturing apparatus,
- wherein the control apparatus comprises:
- a wireless communication device that communicates wirelessly with the strobe;
- and
- a controller that controls the wireless communication device,
- wherein the wireless communication device periodically sends a signal for maintaining communication with the strobe during the exposure period of the image capturing apparatus,
- wherein the wireless communication device stops the signal, then sends a firing trigger signal to the strobe immediately before the exposure period ends.
A control method of controlling a strobe to fire in synchronization with an end of an exposure period of an image capturing apparatus, the method comprising:
- communicating wirelessly with the strobe;
- and
- controlling the wireless communication,
- wherein in the wireless communication, a signal for maintaining communication with the strobe is periodically sent during the exposure period of the image capturing apparatus, and
- wherein in the wireless communication, immediately before the exposure period ends, the signal is stopped, then a firing trigger signal is sent to the strobe.
A computer-readable storage medium in which is stored a program that causes a computer to execute a control method of controlling a strobe to fire in synchronization with an end of an exposure period of an image capturing apparatus, the method comprising:
- communicating wirelessly with the strobe;
- and
- controlling the wireless communication,
- wherein in the wireless communication, a signal for maintaining communication with the strobe is periodically sent during the exposure period of the image capturing apparatus, and
- wherein in the wireless communication, immediately before the exposure period ends, the signal is stopped, then a firing trigger signal is sent to the strobe.
